Tl Ia E SAS WHEEL.

To all whom it may concern.

Be it known that I, WILLIAM BERNARD LLOYD, a citizen of the United States, residing at Yankee, in the county ofColfax and Territory of New Mexico, have invented certain new and useful Improvements in Wheels, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in wheels, especially adapted for use in connection with mine cars, although the improvements are capable of use in other connections, as will be apparent.

The invention has for its object the improvement of means enabling the renewal of the hubs of mine car wheels, so that worn out hubs may be removed and new ones inserted in lieu thereof, in connection with the relatively unimpaired tire rim or tread of the wheels.

The invention also has for its object the provision of a construction a-ifording a practically oil-tight reservoir for lubricant.

A further object is to produce a construction minimizing the wearing friction between the axle and wheels, accomplished by providing a bearing for the wheel of a metal relatively soft compared to the axle.

The invention also embraces as one of its chief characteristics the provision of means for insuring retention of a wheel upon its axle until purposely removed.

WVith the foregoing objects in mind, I have illustrated in the accompanying drawings forming part hereof a convenient embodiment of the invention possessing certain details in arrangement and construction of parts, as will more fully hereinafter appear in connection with the following detailed description, but it will be obvious to those skilled in the art that the invention is capable of embodiment in other forms and devices than that specifically disclosed herein.

In the drawings, Figure l is a vertical sectional view through the wheel, the axle being shown in elevation, Fig. 2 is an end view of the wheel, Fig. 3 is a side elevation of the brass bearings detached, and Fig. 4 is an end view of Fig. 3.

Specification of Letters Patent.

Serial No. 628,846.

Referring more specifically to the drawings, wherein like reference letters refer to the same parts in the several views, A rep resents a car axle having separated annular collars or flanges B, C, formed integral therewith, the latter at the end. of the axle, and the former a suitable distance inwardly from the end of the same.

D represents a two-part bearing, preferably of brass, the body portion of which is cylindrical and of a diameter and length to fit snugly around the bearing portion a of the axle and between the confining collars or flanges B and C. The outer surface of the cylindrical portion of the bearing is tapered in an outward direction, as at d, and the end of this two-part bearing is provided with a corresponding two-part flange E projecting outwardly a substantial distance beyond the collar or flange B, and provided with bolt openings 6.

F is the rim portion of the wheel, the same being provided with a flanged tread for use in connection with suitable rails, as is common in the case of mine car wheels, it being unnecessary to show said rails herein, and Gr is the hub portion usually cast integrally with the rim, the same in this instance being formed hollow as at H to constitute a chamher for lubricant, opening at h to the brasses D and having a fill opening h normally closed by a detachable plug h The bore of the hub portion H is tapered inwardly as at d, so as to have a wedged or binding engagement with the brass bearing D and serving also to create a sealing engagement between the same preventing escape of oil therebetween, it being understood that the oil is supplied to the axle through relatively small openings 72, passing laterally through the brasses to the bearing portion a of the axle.

To securely fasten the wheel against removal from the axle, I provide a series of clamping bolts G',-four being shown,the same passing transversely through apertures g in the hub portion G of the wheel and through the flange E of the brass bearing. The bolts are preferably introduced from the inner side of the wheel, so that the heads clampedflat against the end surface of the; hub portion effectually closes the open end of the latter, and overcomesany possibility By of lubricant escaping .therewithout. lockingthe hub of the :wheelat the -series of points so effectually to the flange E, and the main portions of thebrass bearing to which sald flange'is secured being so firmly seated between the flanges of collars B and C, it is seen that it, is rendered practically impossible that the wheels become accidentally loosened or freed from the axle. I regard thls as an important feature of my improvements.

I'claim:

1. In combination with an axle having separated flange portions, the outer flange being fixed to saidaxle, a bearing member seated between said flange portionsand-having a flange at oneend thereof, a wheel having'a hub portion fittingover said bearing, and fasteningmeanssecuring said hub portion and said flange'of th'e'bearing member together.

2.
